Referring now particularly to FIGS. 1, 2 and 3 of the drawings, it will be observed that the reference character 10 designates, generally, a railway car axle which in FIGS. 2 and 3 is shown by a broken line outline in order to illustrate more clearly the details of construction of the invention. 'The railway car axle 10 includes an axle journal 11 provided with an end collar 12 and it is arranged to rotate about an axis of rotation or its longitudinal axis which is indicated at '13. The axle journal 11 is mounted within a railway car journal box, indicated generally at 14, which is of conventional construction. The railway car journal box 14 includes a horizontal top wall 15 from which vertical side walls 16-46 depend. They are interconnected at their lower ends by a bottom wall 17 which has a concave inner surface 18. This may be a cylindrical surface. The concave inner surface 18 of the bottom wall 17 terminates at its forward end, FIG. 2, in a concave inner surface 19 on the inner side of an end Wall 20 which is located below a lid opening 21 (the lid not being shown). The rear end of the concave inner surface 18 of the bottom wall 17 terminates in a vertical wall 22 of a dust guard well 23 which is completed by a vertical wall 24. Formed integrally with the depending vertical side walls 16-16 are brass stop columns 25-25 having concave surfaces 2626 at their lower ends. The brass stop columns 2525 serve to guide ends 27--27 of a journal brass or hearing 28 which is arranged to engage the surface of the axle journal 11. The journal brass or bearing 28 is surmounted by a wedge 29 which, together with the journal brass or hearing 28, is held in position by a Wedge stop 30 that depends from the under surface of the top wall 15 adjacent the lid opening 21.

In order to limit the lateral movement of the axle journal 11 in the journal box 14, journal guides, shown generally at 33, are provided. They are located along diametrically opposite sides of the axle journal 11 at the elevation of the axis 13 and are four in number. The journal guides 33 of each pair are positioned, as shown in FIGS. 2 and 3, on opposite sides of the respective brass stop column 25 and thus provide a relatively large area for engaging the diametrically opposite sides of the axle journal 11.

' In FIG. 5 there is shown in detail the construction of one of the journal guides 33. Here it will be observed that each journal guide 33 includes a bearing section 34 that maybe formed of forged bronze bearing alloy. It

has a front or bearing face 35 that is juxtaposed to the bearing surface of the axle journal .11. On .the opposite side the bearing section 34 has an integral extension 36 which is telescoped within a support ferrule 37 that may be formed of .pearlitic' malleable iron. The extension 36 is deformed at 33 for the purpose of providing a unitary construction. The "inner surface 33013 the support ferrule 37 is arranged, as shown inure. 3, to bear against the inner surface of the respective side wall 1 6 of the journal box 14.

An annular groove 40 is formed in the suppont ferrule '37 for receiving a .turn 41 of a one piece fspring wire frame that isindicated, generally, at 42. Itwill be understood that the several turnsfll, one for each ofthe journal guides 33, areformed in the one piece spring wireframe 42. Then a support ferrule 37 is inserted in each of the turns Alandthereafter a bearing section 34 is inserted and the extension 36 deformed Ito provide the integral construction shown in'FIG. 5.

Preferably .the one piece spring Wire frame 42;initially is formed of a front section, indicated generally at 43,

and a rear section, indicated generally at 44. Thes sections 43 and 44 are constructed of spring steel wire and, as seen in FIG. 2, they are generally inclined and parallelto each other. Their central portions-45 and 46 are curved, as indicated in FIGS. 1 and 3, in 'order to conform tothe upwardly curved inner surface 18 of the bottom wall 17 of the journal box 14. Therear section d4 has shoulder portions 47- -47, FIG. 3, that are arranged to bear against the adjacent surface of the vertical Wall 22 and thereby limit the inward movement of the spring wire frame 42 assembled with the journal guides 33. I

As seen more clearly in FIGS. 2 and 30f the drawings the front section 43 has lateral portions 515 1 in endwise relation to lateral portions 52-552 of the rear section 44. The ends 53 53 and 5454ex tend tipward-ly in juxtaposed relation intermediate the pairs of journal guides and are held together by retainer clips 5-555 which, as shown in FIG. 6, are d rcnheat pre vide an inverted T-sh-aped configuration overlying the lateral portions 51 51 and 52- -52 of ma ron-t rear sections 43 and 44 with the stern overlying the vertically extending ends 53 -53 and-54 54. The retainer clip 55 is generally U-shaped in cross section and is formed of mild steel. The outer upwardly'extendin g portions are deformed into juxtaposed relation and are secured together in a suitable mannersuchi as spot welding as indicated at 56. i j i It will be understood that the one piece spring wire frame 42 is assembled ,e xt eriorly of the railway c ar journal box 14. The ends are secured together by the retainer clips 55 and the journal guides 33 .are rnounted within the turns or lo o psI41 the manner described.

In order to apply the assembled one piecespning wire frame 42 with the jou nal guides 33, the journal box 14 is elevated by jacking until the hub portion 57 of the axle is engaged bythe walls 22 and 24. permits removal of the journal brass or bearing,2,8 and thelyvedge 29 since the latter is now located below the wedge 30. Next rear section .44 of theq lfl pie e Sp ine wire frame 42 with the journal gnides 33 assemhled therein is inse'rted, as shown in FIGQ4 by full; lines, in the lid opening 21. It is ,moved inwardly through Q16 journal ox 14 to the position shown by broken lines where one corner of the retainer clip SSengages the outer side of thebrass stop column 215. llustlb efore this takes place the front section 43, which ,remains outside of the lid opening' 1, sprung upwardly and inwardly so that, on eonanue'd'mwam movement of the asse nhly, it slides downwardly over the concave inner surface 19 of the end wall and assumesthe ,positionjndicatedmy broken lines in FIG. 4. The assembly then can be moved to the operative position shown in FIG. 2 where the journal guides 33 are held against-the"inner' surfaces being located on opposite sides ofthe brass stop columns 25. Then the journal brass or bearing 28 and Wedge 29 are replaced and finally the journal box 14 is lowered to operative position as shown in FIG. 2. The upper ends of the retainer clips 55 engage the concave surfaces 26-'-26 of the brass stop columns and thereby prevent .rotationof the journal guides 33 and spring wire frame 42 about the axle journal 11.

h 9 free spfins Wir f m assembl h the journal guides 33, can be removed from the journal box 14 bya reversal of the foregoing steps. It will be seen that it is unnecessary to disassemble the car truck side frame including the journal box 14- or to remove the axle 10 from the journal box 14. This reduces material-ly the expense incident to the application of the journal guides '33 and .their removal.

Referring now particularly to FIGS. 7, .8 and 9, it will be observed that the railway car journal .box 14, previously described and having the railway car .axle 10 mounted therein, is provided with journal guides, each being indicated, generally, at .57, which are of a somewhat diiferent construction thanthe journal guides 13 previously described. Each journal guide 57 includes a bearin gseotion :58 that may be formed of forged bronze bearing alloy and is provided with a front or bearing surface -59 that is positioned adjacent the surface of the axle journal 1-1. The bearing section 58 has an integral extension 60' that projects into a support ferrule 61 that may be formed of'pearlite malleable iron. The extension 60 is deformed at 62 for the purpose of securing the bearing section 58 to the support ferrule .61. The support ferrule 61 has a rear surface63 that is arranged to engage the inner surfaces of the depending vertical side walls 16- -16 of the railway car journal box 14.

in order to mount the journal guides 57 a tieplate 64, shown in detail in FIG. 10, is employed. The tie plate 64 may be formed of hot rolled steel andit is provided with rectangular openings65-65 near its ends for receiving a generally rectangular flange 66 that forms an integral part of the support ferrule'ol. In addition the support ferrule 61 is providedwith a centering lug 67 that extends into a slot 68 formed on the innerside of each of the rectangular openings 65. It will be understood that'the tie plate.64 is assembled with two journal guides 57, oneat each end. The support ferrules 61 are positioned on one side of the tie plate 64 with the rectangular flange 66 and centering lug 67 extending into-the rectangular opening 66 andslot68. Then-the bearing sections 58 are applied to the inner side of each tie plate64 with the extension so projecting through the rectangular opening 65 and into the respective support ferrule 61. Thereafter the extension 60 is deformed, as indicated at 62, to provide a unitary construction. The arrangement is uch that thejournal guides 57, when applied to the journal box 14, are'located' on opposite sides of the respective brass stop column-25. i

In order to .hold the journal guides 57 assembled on the-tie plate 64 in operative position in the journal box 14 and to permit the application thereof and removal without removing the journal box 14 from the axle journal 11, a one piece spring wire frame, shown generally at 70 and similar to the spring wire frame 42, is provided. The springwire frame --'7 'ineludes a front section 71 and a rear section 72. These sections include central portions 73 and 74 which are curved to conform to the curvature of the concave inner surface 18 at the bottom ofthe journal box 14-. The rear section 72 of the one piece spring wire 'frame 79 includes shoulder portions 72'-72 that bear against the outer side of the vertical wall 22 and serve to limit the movement of the spring wire frame 70 into the journal box 14. From the shoulder portions 72' :72 horizontal portions 75 75'extend to a position to the left of the inner journal guide 57 as seen in FIG. 8. Upstandingportions 7777 and 78-78 extend from the front section 71 and from the horizontal portions 7575 along the inner surfaces of the walls 16--16 of the journal box 14. At the upper ends of the upstanding portions 77 and 78 there are forwardly extending portions 77'--77 and 7878', FIG. 9, that are directed toward the central portion of the journal box 14. From the inner ends of these forwardly extending portions 77 and 78' there are lateral portions 79-79 and 80Eit) which overlie the outer side of each of the tie plates 64. These lateral portions 79 and 80 extend toward each other as best seen in FIG. 8 and terminate in upstanding end portions 81-81 and 8282 which also overlie the outer sides of the tie plate 64. The lateral portions 79 and 80 with the up standing end portions 81 and 82 form an inverted T- shaped configuration with the extreme ends 83-83 and 84-84 extending toward the concave surfaces 26Z6 and engaging the same as shown in FIG. 7. This arrangement with the end portions 83 and 84 juxtaposed to the concave surfaces Z626 serve to prevent movement of the spring'wire frame 70 and the journal guides 57 carried thereby in either direction around the axle journal 11.

In order to ecure the juxtaposed lateral portions 79 and 8t) and upstanding end portions 81 and 82. of the sections 71 and 72 of the spring wire frame 70 to the outer sides of the tie plates 64 a wire retainer cover plate or clip 85, preferably formed of mild steel, is employed. Each cover plate or clip 85 is formed with an inverted T-shaped groove 86, FIG. 8, in order to permit the juxtaposed faces of the tie plates 64 and cover plates or clips 85 to come into surface contact engagement. They are held together by projection welding which is facilitated by the provision of projections 87, FIG. 10, preferably four in number. In order to accurately locate the cover plate or clip 85 a locater. lug 88, FIG. 10, is deformed therefrom and is arranged to enter an aperture (not shown) in the adjacent cover plate or clip 85.

' After the journal guides 57 have been assembled with the tie plate 64 in the manner described, the front and rear sections 71 and 72 of the spring wire frame 70 are positioned in the relationship shown in FIGS. 7, 8 and 9 in a suitable jig and the cover plates or clips 85 are properly positioned and clamped in place. Then, by projection welding, the cover plates 85 are welded to the tie plates 64 in order to provide a unitary construction,

The manner in which the one piece spring wire frame 70 assembled with the journal guides 57 is applied to and removed from the journal box 14 is essentially the same as described hereinbefore for the one piece spring wire frame 42 having the journal guides 33 assembled thereon. An important advantage of the use of the tie plate 64 is thatit securely holds the journal guides 57 in position inside the journal box 14. Also it facilitates the action of the spring wire frame 70 in urging the journal guides 57 into good contact engagement with the side walls 1616.

There are some journal boxes 14 that are oversize a slight amount. In order to employ the same assembly of the spring wire frame '70 and journal guides 57 provision is made as shown in FIGS. 11 and 12 for positioning a shim 91 behind each support ferrule 61 and between its rear surface 63 and the adjacent surface of the side wall 16. The shim 91 is formed of suitable metal and include ears 9292 that can be turned over a laterally extending flange 93 at the outer side and outer end of the support ferrule 61. A lug 94, on the opposite side of the shim 91, overlies the adjacent surface of the support ferrule 61 and serves to hold the shim in position.
